Title: Production of microbial cellulose
Inventor: FUKAYA MASAHIRO
IPC: C12P19/04
Filed: 1992-04-21
Abstract: PURPOSE:To obtain the subject cellulose in high efficiency and improved yield by inoculating a microbial strain belonging to the genus Acetobacter and capable of producing microbial cellulose on a specific medium, subjecting the strain to standing culture while keeping the carbon source to a low concentration and collecting the produced and accumulated substance. CONSTITUTION:A microbial strain belonging to the genus Acetobacter and capable of producing microbial cellulose (e.g. Acetobacter pasteurianus ATCC 10245) is inoculated on a medium for the production of microbial cellulose and cultured by standing culture at 30 deg.C for 192 hr while keeping the concentration of the carbon source (e.g. glucose) in the medium at a low level (i.e., <=2 g/L) during the culture period and continuously supplying a liquid having a carbon source concentration of 40% at a rate of 0.26 mL/h for replenishing the consumed carbon source. The microbial cellulose produced and accumulated on the surface of the culture liquid is separated by filtration, immersed in 1% NaOH aqueous solution at room temperature for 24 hr to remove the protein and neutralized to obtain the objective microbial cellulose.

Title: Protective circuit for semiconductor integrated circuit device
Inventor: TAKAHASHI TOYOFUMI
IPC: H01L21/8234
Filed: 1987-05-23
Abstract: PURPOSE:To form a protective circuit which has a large effect by using the small area of a semiconductor substrate by forming a ringlike diffused layer around a diffused layer formed under a pad or a diffused layer connected to the pad, and composing the protective circuit of a protective transistor or the like by both the diffused layers. CONSTITUTION:Since the gate electrode 12 of a MOS transistor 19 is a ground potential and a gate-source voltage is 0V, the transistor 19 is normally OFF. When a positive surge voltage is applied to a pad 16, a current flows from a drain 6 to a source 8 by a source-drain punch-through characteristic, a breakdown occurs between a diffused layer 6 and a substrate 2, and a current flows from the pad 16 to the substrate 2. When a negative surge voltage is applied to the pad 16, the transistor 19 of this protective circuit becomes ON, a current flows from the source 8 to the drain 6, or a current flows from the substrate 2 to the pad 16 by the forward direction of a diode. Since a N-channel MOS transistor which becomes a protective device is composed in a ring shape around the pad 16 in this manner, the protective circuit having a large effect can be obtained by a small chip area.

Title: Vacuum cleaner
Inventor: NAKAO HIROSHI
IPC: A47L9/00
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum cleaner in which the performance of attachment/ detachment of a dust collecting filter of a vacuum cleaner can be improved and the airtightness between the dust collecting filter and a main body can be ensured. SOLUTION: The vacuum cleaner has a freely detachable dust collecting filter 14 collecting the dust sucked from an inlet port toward the suction side of an electric blower storage part 13. The electric vacuum cleaner has a filter holding body 15 that is attachable and detachable and is formed to press-contact and hold the dust collecting filter 14 toward a main body 11. The attaching and detaching direction 17 of the filter holding body 15 is set so that it slants against the press-contact direction 16 of the dust collecting filter 14, thereby since the filter holding body 15 is attached from the slant direction to the press-contact direction 16 of the dust collecting filter 14, the dust collecting filter 14 can be strongly press-contacted toward the main body 11 without getting caught, and a high airtightness can be ensured.  Also, the direction of the load applied on the filter holding body 15 differs from the detaching direction of the filter holding body 15, thereby it is not necessary to firmly fit the filter holding body 15 into the main body 11 under the apprehension that the filter holding body 15 may be released.

IPC: G02B6/38
Filed: 1983-07-12
Abstract: PURPOSE:To recover sufficiently and easily a mechanical strength of an optical fiber, which has dropped by a connecting work, and to secure the strength held before the connecting work by etching the surface of a welding and connecting part of the fiber by means of opposite spattering, and thereafter, forming a thin film of an inorganic matter by spattering. CONSTITUTION:Voltage is applied between fibers 5, 5' and an electrode 9, and opposite spattering (spatter-etching) is executed. As a result, impurities adhering to the surface of a connecting part are removed (ion cleaning), also the ion etching is executed to the surface of the fibers 5, 5', and a surface layer part on which a flaw exists is removed. Subsequently, voltage is applied between an electrode 10 of an inorganic matter consisting of a metal such as aluminum, etc., and silica, etc., and the fibers 5, 5', and spattering is executed. As a result, a protective thin film by the inorganic matter of a single layer or a multi-layer is formed on the surface of the connecting part. In this way, a flaw of the surface layer does not exist on the welding connection part, and also it is covered with the protective film, therefore, the mechanical strength of the fibers 5, 5' becomes a strength in the same degree as before the connecting work, or the strength exceeding it.

Title: Production of al killed base cold rolled high tensile steel plate
Inventor: SATOU MASUHIRO
IPC: C21D8/02
Filed: 1979-10-02
Abstract: PURPOSE:To produce an Al killed base cold rolled high tensile steel plate of superior workability and of the strength improved by baked coating or the like by hot rolling, cold rolling and annealing the Al killed steel contained with a fixed amount of P and defined of an Mn amount under the specific conditions. CONSTITUTION:The Al killed steel slab contg. <0.2% Mn, <=0.15% C, 0.04%<= P<=0.15%, 0.015%<=Al<=0.1%, and 0.002%<=N<=0.008% is hot rolled. The finishing temperature is kept at above the Ar3 transformation point and the coiling temperature is kept at <=700 deg.C, so that it is maintained in a solid solution state without allowing AlN to deposit. Next, scale is removed by pickling or the like, and the plate is cold rolled at >=40% draft, to make tensile strength, surface characteristic and workability highest possible. Further, it is annealed at a high temperature above the recrystallization temperature, after which it is cooled at a cooling rate of >= 0.15T deg.C/hr when the passage temperature during cooling is defined as T deg.C. The workability and baking hardness improve, and consequently, the steel plate of superior dent resistance for automobile planks is obtained.

Title: Clutch mechanism
Inventor: NAGAHARA TADASHI
IPC: F16D21/00
Filed: 1978-10-17
Abstract: PURPOSE: To change the direction of power transmission without using any external power source, by using the internal power from a driving source such as motor also for the transmission control.  
     CONSTITUTION: When a driving gear 4 is reversed by reversing a motor 1, the transfer reaction force R' of a transmission gear 23 is turned upward, a lever 21 is turned in the direction of arrow F and the transmission gear 23 is disengaged with an output gear 6a. The reaction force is canceled with this disengagement to make the gear 23 freely swivel. However, the rotational friction given from a slip ring 25 to the transmission gear 23 generates a reaction force (in the same direction as the reaction force R') to keep the lever 21 turn in the direction of arrow F. In other words, the gear 23 moves round a driving gear 4 while turning on its own axis, and the lever 21 makes a 180 deg turn counterclockwise until it hits a stopper 26b.

Filed: 1987-05-27
Abstract: PURPOSE:To find trouble of an optical star coupler in the early stage by using an optical signal different in wavelength from an information transmission signal to form a processing loop for detection of trouble of the optical star coupler. CONSTITUTION:Data for trouble detection is outputted from a trouble detecting part 60, and a wavelength lambda1 from an electrooptical transducer (E/O) 24 and a wavelength lambda2 from an E/O 61 are multiplexed by an optical multiplexer 62, and the output of this multiplexer is inputted to an optical star coupler 1. The multiplexed wavelength from the coupler 1 is demultiplexed by a demultiplexer 63, and the optical signal having the wavelength lambda2 is converted to a corresponding electric signal by an O/E 64 and is inputted to the trouble detecting part 60. The input signal coincides with data for trouble detection outputted to the E/O 61 if trouble does not occur in the coupler 1, but it does not coincide with this data if trouble occurs in the coupler 1. The discrimination re sult of the detecting part 60 is reported to a controller 21, and the occurrence of trouble of the coupler 1 is indicated with an alarm by an alarm device 65 and a plant is operated to the safety side.

Title: Switching power amplifier circuit
Inventor: YOSHIDA TETSUO
IPC: H03F3/217
Filed: 1985-06-14
Abstract: PURPOSE:To relax the required characteristic of a low-pass filter (LPF) by extracting a component of a stop band of the LPF restoring a signal power from a PWM waveform and impressing the component to a signal superimposing means connected to the output of the LPF via an amplifier so as to cancel the component of the output stop band of the LPF. CONSTITUTION:The low-pass filter consists of L and C and restores a fluctuation signal waveform from a PWM waveform and gives a power to a resistor RL. Only a high frequency component only is extracted from a voltage across the capacitor C by a high-pass filter 5 and power-amplified by a wide band AC amplifier 6 and the result is inputted to a primary winding of a transformer T. The secondary winding of the transformer T is inserted between the low-pass filter output and the load RL in the polarity cancelling the high frequency ripple voltage of the low-pass filter output thereby suppressing the noise having an undesired PWM frequency. Since the high-pass filter 5 need not to pass power and has only to divide the output of the low-pass filter and processes a low level signal, a high characteristic is realized easily. Further, the transformer T treats a high frequency component only and the amplitude is small, then the small shape can be realized.
